The
trommel screen is a special screening equipment developed for building materials, metallurgy, chemical industry, mining and other industries. It overcomes the blockage problem of circular vibrating screen and linear vibrating screen when screening wet materials and improves the output of the screening system And reliability, it is widely used in the separation of sand and gravel in the sand and rock yard, as well as the size and particle size classification and the separation of lump powder in the chemical industry and mineral processing industry.
The trommel is a relatively large processing equipment in the screening equipment. Although there is no complicated structure such as a magnetic separator and a sorting machine, the processing capacity is relatively large during use. Therefore, it is inevitable that some mechanical problems will inevitably occur during long-term use. Today, the editor summarizes the following more important and prone faults, and gives the corresponding solutions, hoping to help you.
1. Noise problems caused by loose equipment bolts
Solution: re-tighten bolts or other fasteners;
2. Wrong direction of rotation caused by wrong connection of motor power cable
Solution: Replace the power cable in the junction box;
3. The problem of slow start-up caused by motor overload or excessive conveying volume
Solution: readjust the delivery volume;
4. Insufficient ventilation or lack of lubricant in the box makes the gear box heating problem
Solution: Check and adjust the heat dissipation of the vents and add lubricant;
5. Motor heating problem
Solution:
(1) Clean the heat sink of the motor;
(2) Check whether the fan impeller is working properly to ensure smooth air circulation;
(3) Reduce the load;
(4) Fasten the connection;
(5) Re-wiring after checking.
6. The sieve hole is blocked so that the drum screen cannot operate normally
Solution: Clean up the garbage clogged in the sieve in time to reduce clogging.
